Fig. 7 and Fig. 8 are the schematic top plan view according to the three-dimensional display after laminating of one embodiment of the invention.
In order clearly to illustrate the relation of display panel 110 and shielding panel 150, Fig. 7 only shows display panel 110 and has omitted other members with the edge of shielding panel 150.In general,, in the time that display panel 110 and shielding panel 150 are fitted, because the aligning accuracy of slice applying machine bench is not good, therefore there is the problem of rotation error.Please refer to Fig. 7, in the present embodiment, the resolution of display panel 110 is A × C, and A<C, and A is that quantity (being minor face size) and the C of time pixel cell S in every a line is the quantity (i.e. long limit size) of time pixel cell S in each row.Bit errors between display panel 110 and shielding panel 150 rotation threshold values is 2 θ (that is, the angle at the edge of the edge of display panel 110 and shielding panel 150), and wherein 2 θ meet following formula:
P represents the width of one pixel cell S, and D represents the bit errors threshold values between display panel 110 and shielding panel 150, and 0.005 Du ≦ θ≤0.05 degree.For instance, A is that 720, C is 1280, and P is 77.1 μ m, and, in the time that D is 5 μ m, θ is 0.0052 degree; In the time that D is 50 μ m, θ is 0.052 degree.
In more detail, display panel 110 is rectangle and has first side 110a.Shielding panel 150 is for rectangle and have second side 150a, and wherein first side 110a and second side 150a form acute angle 2 θ, and acute angle 2 θ are 0.01 degree to 0.1 degree.That is to say, because the aligning accuracy of slice applying machine bench is not good, therefore generally can between the first side of display panel 110 110a and the second side 150a of shielding panel 150, form acute angle, and the maximal value of the acute angle that described bit errors causes is 2 θ, wherein 0.005 Du ≦ θ≤0.05 degree (in fact, this 2 θ value can be different according to the aligning accuracy difference of different slice applying machine benchs).
Moreover, in order clearly to illustrate the relation of the inferior pixel cell S of display panel 110 and the electrode of shielding panel 150, Fig. 8 only shows the inferior pixel cell S of display panel 110 and the first electrode 164 of shielding panel 150 and the second electrode 174 and has omitted other members.
It is worth mentioning that, please refer to Fig. 8, in the present embodiment, the angle between the bearing of trend of the first electrode 164 and the bearing of trend of the second electrode 174 is θ 1+ θ 2=2 θ.Therefore, in the time that the bit errors rotation threshold values between display panel 110 and shielding panel 150 is 2 θ (that is, when the aligning accuracy of slice applying machine bench not accurate enough and while thering is rotation error value, for example, when accurately not fitting and thering is rotation error), the side 164a of the first electrode 164 can be along Y-direction extension and parallel with the side Sa of inferior pixel cell S, and the angle that the side 164a of the side 174a of the second electrode 174 and the first electrode 164 forms is 2 θ, wherein 0.005 Du ≦ θ≤0.05 degree.
Also it is worth mentioning that, in the present embodiment, can be after display panel 110 and shielding panel 150 be fitted, selection and Y-direction (that is, laminating centerline direction) the less electrode of deviation angle as guarded electrode, the larger electrode of the deviation angle of another and Y-direction is as common electrode.In more detail, in the present embodiment, due to the side 164a of the first electrode 164 can along Y-direction extend and parallel with the side Sa of inferior pixel cell S (that is, the first electrode 164 is less with the deviation angle of Y-direction), therefore can be using the first electrode 164 as guarded electrode, another second electrode 174 is as common electrode.Thus, can make the guarded electrode of strip and the inferior pixel cell S accurate contraposition of every a line, and then can avoid the guarded electrode skew that bit errors causes and fail to cover completely the problem of light leak, colour cast and noise that the inferior pixel cell S of below causes.
In the embodiment of above-mentioned Fig. 7 and Fig. 8, be not to be that accurate contraposition fits into example explanation with display panel 110 and shielding panel 150, but the invention is not restricted to this.In other embodiment (as shown in the embodiment of Fig. 9), display panel 110 can also be accurate contraposition laminating with shielding panel 150.
Please refer to Fig. 9, in the time that the bit errors rotation threshold values between display panel 110 and shielding panel 150 is 0 (that is, when the rotation error value of the aligning accuracy of slice applying machine bench hour, for example, while accurately laminating), the side 174a of the side 164a of the first electrode 164 and the second electrode 174 is θ with the angle that the side Sa (or Y-direction) of inferior pixel cell S forms respectively, wherein 0.005 Du ≦ θ≤0.05 degree.
As mentioned above, due to the bearing of trend of the first electrode 164 of the present invention and the bearing of trend of the second electrode 174 respectively and between Y-direction, there is the design of angle, and this angle is that the bit errors between display panel 110 and shielding panel 150 is rotated 1/2nd of threshold values 2 θ, therefore no matter whether accurate contraposition laminating all can reach the effect that improves aligning accuracy.That is to say, aligning accuracy of the present invention is increased to and is less than or equal to θ, and 0.005 Du ≦ θ≤0.05 degree.
In the embodiment of above-mentioned Fig. 4 to Fig. 9, be to there is respectively one deck electrode structure take the first electrode layer 162 and the second electrode lay 172 to illustrate as example, but the invention is not restricted to this.In other embodiment (as shown in the embodiment of Figure 10 and Figure 11), the first electrode layer and the second electrode lay can also be the electrode structures having more than one deck.
Figure 10 and Figure 11 are the diagrammatic cross-sections according to the shielding panel of other embodiment of the present invention.The embodiment of Figure 10 and Figure 11 is similar to the embodiment of above-mentioned Fig. 4, and therefore same or analogous element represents with same or analogous symbol, and no longer repeat specification.
